Yes, but please be sure the fitting you have is BSP and not NPT, BSP (British Standard Pipe) is the European standard, NPT (National Pipe Thread) is the US standard and if you try to thread in NPT, it is very likely the pump housing will crack and it won't seal. BSP is generally difficult to source in the US, it is definitely available but will require some searching online, it won't be readily available at a hardware store like NPT.
